Application filed February a, 1224; elm-nin centra l To all whom 2'2? may concern: 7

Be it known that we, AJISTIN (l UDMUND- sun and HIRAM VVILLIAM CLARK, citizens of the United States, residing at Salt Lake City, in the county of Salt Lake and. State of Utah, have invented a new and useful Device for Furnaces, of which the following is a specification.

This invention relates to apparatus for converting a plain updraft furnace into a furnace capable of burning soft coal e nomically and smokelessly.

The object of the invention is to equip a furnace with a comparatively thin eurtain wall so constructed as to afford ready access to the fines and boiler tubes for cleaning and other purposes.

Another object is to provide a curtain wall of the character above set forth made up of a plurality of segments and constructed in such a manner that warped, broken or burned segments may be replaced with out removing the others.

vVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings:

Figure 1 represents a front elevation of a furnace with the front wall removed and showing the curtain constituting this in vention applied.

Fig.2 is a longitudinal. section the line 2-2 of Fig. 1.

Fig. 8 is a top plan View of the channel support.

Fig. 4 is a front elevation of one segment of the curtain.

Fig. 5 is an end elevation thereof.

Fig. 6 is an enlarged detail end view of the upper portion of the curtain; and

Fig. 7 is a top plan View of the curtain detached.

In the embodiment illustrated a furnace F is shown which is preferably of steel, a fire-box of the fire-tube boiler type and extended transversely across which is the curtain wall 1 constituting this invention. This taken on wall 1 extends from. ileto side of the furnace'and from the top thereof down tia point ad acent the grate '(rbeing paced from said grate. This curtainj 1 depends from the topj'of the fire-i box'and is com posedof a plurality of segments two beinghere shown and numbered 2 and. 3 respectively. These segments 2 and 3 are sup ported so that one may be moved relatively to the other said segments being slidable one past the other to adapt an opening to be formed by the movement of one without interfering with the other. These segments 2 and 3 are constructed as shown in detail. in Figs. i and 5 having solid backs 3 with intersecting ribs 4 and 5 on the front face thereof which form recesses or pockets 6 to receive a refractory filling 7. The cross ribs l and 5 prevent the body of the segment from warping. The material from which these segments are made is preferably cast iron and the base or lower bar 8 thereof is made comparatively wide and thick as shown in Fig. 5. These segments are not necessarily constructed of cast iron but may be made of a suitable refractory material or combination of cast iron and refractory material, or may be made of cast iron only.

The segments are equipped at their upper ends with longitudinally spaced hooks 9 which are offset from the body portionof the segment as shown clearly in Figs. 5 and 6. The hooks may also be equipped with rollers 9 to roll on the channel support. These hooks 9 are designed to be engaged with the side flange of a channel iron or beam 10 suspended from the top of the furnace by any suitable means bolts 11 being here shown.

These segments 2 and 3 are arranged back to back with one end of one lapping the adjacent end of the other and the supporting books of one engaged with one side flange of the channel beam While those of the other segment are engaged with the other flange as shown clearly in Fig. 2 so that one segment may be moved longitudinally on said beam without interfering with the other.

It is of course understood that any desired number of segments may be employed according to their sizes and the width of the furnace in connection with which they are to be used. The segments on either side of the channel bar need not be distributed yininetrically but may be arranged in any 15 furnace having a firebox, a channel iron sup-.

ported within the firebox, partitioning n1eruhers having their upper ends constructed to provide spaced hooks, rollers supported by the hooks, said rollers adapted to more over the flanges of the channel iron at opposite sides of the channel iron, said parlitioning members adapted to provide a 1novable partitioningmember across the upper portion of the firebox.

In testimony that we claim the foregoing as our own, we have hereto aiiixed our signatures.
